Now with commit 9c7dafb (net: Allow to create links with
given ifindex) support registration of network devices
with specific ifindex is added.
We can force loopback network device index before call to
register_netdev() to ensure we always configure it with
LOOPBACK_IFINDEX.
Kill BUG_ON() since system can continue without network
namespace failed in loopback init path, unless it is
init_net namespace where we panic() anyway.
